According to tweets from an editor of the Spectator newspaper, “something serious” just happened on London Bridge in the U.K., with one witness reportedly saying it was like the March terror attack on Westminster Bridge “all over again.”

LONDON BRIDGE UPDATE – Police are dealing with a major incident and all routes are being diverted.

Police aren’t saying much yet, but they’re treating the stabbings at Borough Market as a second incident and confirming a third in Vauxhall. The gunshots many have been reporting seem to have come from the police responding to the attacks at Borough Market.
